Medicare’s annual enrollment period (AEP) is from October 15th through December 7th. This is your opportunity to change your health plan for the next calendar year.

Additionally, Medicare has a Medicare Advantage (MA) Open Enrollment Period, this is for those who are already in a MA plan, from January 1st through March 31st. During this time period you may do the following:

  • Switch to another Medicare Advantage Plan with or without drug coverage
  • Drop your Medicare Advantage Plan and go back to Original Medicare
  • Join a Medicare drug plan

Accepted Medicare and Medicare Advantage Plans for 2026

NorthBay Health is actively working to finalize our in-network status with Medicare Advantage plans. We understand how important it is for you to have clarity about your coverage, and we appreciate your patience as we complete this process. Updates will be shared on this page within the next 10–14 days.

In the meantime, please know that NorthBay Health is already in-network with the following:

  • Original Medicare
  • Medicare Supplements, plans A-N (such as TriCare for Life, AARP Medicare Supplement, USAA Medicare Supplement, Mutual of Omaha, etc.)
  • For accepted employer sponsored retiree plans, please visit our accepted health plans page

Don't see your plan listed?

If you do not see your plan listed here, it means either:

  1. Our hospital group (NorthBay Health Medical Center and NorthBay Health VacaValley Hospital) is not in-network.
  2. Our medical group is not in-network.
  3. Our hospital and our medical group are not in-network.

If you have a Medicare Advantage PPO plan, and you have out-of-network benefits, you can be seen and you will have a higher out-of-pocket cost.

Why choose a Medicare Advantage plan?

Medicare Advantage plans offer more benefits than Original Medicare including prescription drug coverage (Part D), and others such as dental, vision and over-the-counter allowance.

If your current plan doesn't offer the benefits and features you are looking for, it may be time to switch to a new Medicare plan.
